Fragment Spray (Ex): Once every minute a mosaican can let out a 20-foot cone of jagged stones that imbed themselves in their victim's skin, dealing piercing and slashing damage equal to its slam damage, a successful reflex save halves (DC = 10 + half mosaican's HD + strength modifier). The bits of stone within the wounds then pull themselves loose, causing an additional 1d4 damage. They form together, flying back towards the mosaican that sent them, and are reabsorbed. Treadeasy (Ex): As a full round action a mosaican spread out upon the floor can abruptly spring up sharp stones into those transversing upon it, automatically dealing damage as caltrops for the space it occupies. It may then trip any of those who occupy its space by suddenly moving forward. To avoid being tripped its opponent must make a successful reflex save (DC 10 + 1 per 20 feet it moves. Example: A creature with a base speed of 30 feet can run 4 times that, for a speed of 120 feet per round. The save DC would thus be 16.) Artistic Touch (Sp):At will a mosaican may use a type of prestidigitation that allows it to change its colors to match its image(s), make itself appear soiled, old, cracked, damaged, or even newly laid, sparkling clean and flawless. Animate Scene (Ex): As a full round action a mosaican can reasemble its natural form (a flat surface scene) to a life-sized version of its original guardian image, or vice versa. Beforehand it is indistinguishable from a normal mosaic scene unless Detect Magic or similiar spells are used. While in its flat form it loses all its attacks, but can then use its treadeasy ability. Construct Traits: A mosaican has immunity to poison, sleep effects, paralysis, stunning, disease, death effects, mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects), and any effects that requires a Fortitude save unless it also works on objects or is harmless. It is not subject to extram damage from critical hits, nonlethal damage, ability damage, ability drain, fatigue, exhaustion, or energy drain. Cannot heal damage, but can be repaired. It has darkvision out to 60 feet and low-light vision. Immunity to Magic (Ex):
A mosaican is immune to any spell or spell-like ability that allows spell resistance. In addition, certain spells and effects function differently against the creature, as noted below.
A transmute rock to mud spell slows a mosaican (as the slow spell) for 2d6 rounds, with no saving throw, while transmute mud to rock heals all of its lost hit points.
A stone to flesh spell does not actually change the mosaican's structure but negates its damage reduction and immunity to magic for 1 full round. Tremorsense (Ex): A mosaican can automatically sense the location of anything within 60 feet that is in contact with the ground, wall, or ceiling, so long as it is touching the ground, wall, or ceiling itself.
Up the Walls (Su): A mosaican can climb and travel on vertical surfaces or even traverse ceilings as if under the affects of a Spider Climb spell, but only while in its flat form. It gains a climb speed equal to its base speed; furthermore, it need not make Climb checks to traverse a vertical or horizontal surface (even upside down). The mosaican retains its Dexterity bonus to Armor Class (if any) while climbing, and opponents get no special bonus to their attacks against it. It can use the run action while climbing.
The mosaican's passage while flat against a service is soundless.
